QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Plant Hormones.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 10

A plant is exposed to light from one side only. Which hormone will redistribute to the shaded side, causing the plant to bend toward the light?
A scientist applies a hormone to a plant and observes increased cell elongation in the stem. Which hormone was most likely applied?
Describe how ethylene affects fruit ripening.
